Ok, I am going to post two pics and I am waiting on more (back, triggers and light bar). I compared measurements to the current DS4, and it appears the grips on this mockup/prototype/or elaborate fake are indeed fatter. One thing that is making me a little suspicious, is that the connection ports are the same as the DS4, but that could be for legacy usage, and the extra "hole" Cerny mentioned does not appear to be present like the patent pictures. Now that could be either moved to a different location, thus waiting on more pics.
Otherwise, outside of a few minor perceivable aesthetic differences, it appears to look the same. And why on a Vaio? I thought they were out of production, at least with the Sony branding, no?
I will let Detective GAF do their diligence:
